Bug fixing for website which is converted to android app

I have one website [login to view URL] which I have converted into Android app sing website appstrand.com. The app is in android store on the link [login to view URL] Appstrand as per their opinion has just provided web view of site in app. Ths issue is on one browser I am not facing issue related to popup & select all ( select all selects all rows). But I am facing the issue related to popup & select all on android app. When I checked with Appstrand support team they told that it is issue in the coding for java script/ jquery Below is the step to repicate. Login to [login to view URL] with id dc@[login to view URL] & Password Kcfve999* Then click on button "Step 2 Send SMS to Customers" then click on select all. It will select all rows. This select all functionality is not working on Android App. Also when you click on "Write Message" popup is coming. The same popup is not coming on android app. Appstrand support team they told that it is issue in the coding for java script/ jquery at my website which need to be fixed. I want this functionality working on Android app as well. Please bid if you have already worked on such issues & can solve this in one day.
